1. Crate Training
Crates are very popular pieces of equipment these days. I use crates or pens when my puppies are young as places for them to rest during the day (with the door closed) as well as overnight too. My vehicle also has permanent fixed crates for them to travel inside safely when we're out and about.
When used well they can be safe spaces where dogs will choose to rest, and can be helpful in getting dogs used to periods of separation from their owner.
But unfortunately crates are often used very badly and result in unhappy, stressed dogs :(
Here's my advice should you want to use a crate your dog at any point.
